Abstract
U posljednjih trideset godina, prijenosna rendgenska fluorescencija razvila se od prototipa do ključne tehnike za terenske geokemijske analize, posebice za rudarstvo, pedologiju i primjenu u analizi okoliša. pXRF je prva analitička tehnika koja je omogućila pružanje informacija na terenu i time je prekinuta vremenska barijera između uzorkovanja, rezultata i donošenja odluka. Osim vremenske učinkovitosti, pXRF je neinvanzivna tehnologija koja nema utjecaj na okoliš. Osigurava brzu,... More nedestruktivnu analizu širokog raspona elemenata (od Mg do U) iz različitih medija za koje nije potrebna ili je potrebna minimalna priprema uzorka. Cilj ovog rada bio je testirati metodu izravne kvantifikacije ukupnih koncentracija elemenata (K, Ca, Cu, Pb, Zn, Ni, Mo, Sn, As, Fe, Co, Cr, Mn, Zr, Sr, Rb i Nb) u tlima pomoću pXRF analizatora te utvrditi točnost rezultata analize s obzirom na rezultate ostvarene klasičnim analitičkim laboratorijskim tehnikama. Za potrebe istraživanja, korišten je pXRF analizator kojim su se utvrdile ukupne koncentracije sedamnaest elemenata (K, Ca, Cu, Pb, Zn, Ni, Mo, Sn, As, Fe, Co, Cr, Mn, Zr, Sr, Rb i Nb) u četrdeset i tri (43) referentna uzorka tla različitih teksturnih klasa (WEPAL, Nizozemska). Statistička obrada podataka obuhvatila je izračun medijana, standardne devijacije (SD), koeficijenta varijacije (CV), srednje kvadratne pogreške aritmetičke sredine (RMSE) i Pearsonovog korelacijskog koeficijenta. Dobiveni rezultati istraživanja ukazuju na potpunu korelaciju (r > 0,90) pXRF analize i klasičnih laboratorijskih tehnika pri analizi K, Ca, Fe, Mn, Ni, Cu, Zn, As, Rb, Sr, Nb, Zr i Pb, vrlo jaku korelaciju (r = 0,8303) pXRF analize i klasičnih laboratorijskih tehnika pri analizi Cr te na nemogućnost očitanja Sn, Co i Mo čije su vrijednosti bile ispod granice detekcije mjernog instrumenta.

Abstract (english)
In the last thirty years, portable X-ray fluorescence (pXRF) has grown from prototype to a key technique for field geochemical analyses, especially for mining, soil science and environmental applications. pXRF was the first analytical technique able to provide on-site information and in so doing broke the time barrier between sampling, results and decisions. Besides its time efficiency, pXRF was also identified as a non-invasive, low environmental footprint technology. It... More provides rapid, non-destructive analysis of a wide range of elements (Mg to U) from different materials that don`t require or require minimal sample preparation. The aim of this study was to test the method of direct quantification of total element concentrations (K, Ca, Cu, Pb, Zn, Ni, Mo, Sn, As, Fe, Co, Cr, Mn, Zr, Sr, Rb, and Nb) in soils using pXRF analyzer and to determine the accuracy of the analysis results considering the results obtained from classical analytical laboratory techniques. For research purposes, a pXRF analyzer was used to determine the total concentrations of seventeen elements (K, Ca, Cu, Pb, Zn, Ni, Mo, Sn, As, Fe, Co, Cr, Mn, Zr, Sr, Rb, and Nb ) in forty-three (43) referent soil samples with different texture classes (WEPAL, The Netherlands). Statistical analysis included calculation of the median, standard deviation (SD), coefficient of variation (CV), root mean square error (RMSE) and Pearson's correlation coefficient. The obtained results show following: very high correlation (r > 0.90) between pXRF-analysis and traditional laboratory techniques in the analysis of K, Ca, Fe, Mn, Ni, Cu, Zn, As, Rb, Sr, Nb, Zr and Pb, high correlation (r = 0.8303) between pXRF-analysis and traditional laboratory techniques for Cr analysis and inability to determine Sn, Co, and Mo which were below the limit of detection (LOD).
